<html><head>
<style>
*{margin:0;padding:0;}
ul{
list-style:none;
}
#menu{
width:860px;
margin:55px auto;
font-size:13px;
border:1px solid orange;
overflow:hidden;
}
#tabMenu{
background:orange;
height:30px;
width:870px;
}
#tabMenu li{
float:left;
line-height:30px;
width:143px;
background:#fdceff;
margin-right:1px;
text-align:center;
}
#tabMenu .bgcaption{
background:#fbb7fd;
color:#fff;
font-weight:bold;
}
#tabContent{
width:860px;
position:relative;
height:100px;
}
#tabContent ul{
background:#fbb7fd;
width:144px;
position:absolute;
top:0;
left:0;
}
#tabContent .current{
display:block;
}
#tabContent .normal{
display:none;
}
</style>
<script type="text/javascript">
function tabChange(num){
var tabMenu = document.getElementById("tabMenu");
var tablist = tabMenu.getElementsByTagName("li");
for(var i=0; i<tablist.length; i++){
var m = i+1;
if(i == num){
document.getElementById("list_"+m).className ="current";
tablist[i].className = "bgcaption";
document.getElementById("list_"+m).style.left = num*144+"px";
}
else{
document.getElementById("list_"+m).className ="normal";
tablist[i].className = ""
}
var content = document.getElementById("tabContent")
var list = content.getElementsByTagName("ul")
list[i].oumouseout = function(){
this.className ="normal";
}
}
}
</script>
